The first billing app built around how stone is actually sold — by the
square foot, one slab at a time
The first billing app built around how stone is actually sold — by the
square foot, one slab at a time. MarBill turns Length × Height × pieces
into accurate sq.ft, applies your GST automatically, and lets you share
the PDF on WhatsApp in one tap.
WHY MARBLE & GRANITE TRADERS PICK MARBILL
• Sq.ft-native line entry. Add a slab: pick variety → type L × H × pcs →
area + amount appears live. Multiple pieces of the same stone roll up
to one invoice line.
• GST done right. CGST + SGST for intra-state customers, IGST for
inter-state — switches automatically based on your state and theirs.
Round-off to the rupee, deterministic to the paisa.
• Mobile-first, no desktop required. Built for your phone. Bill while
walking the godown. Send the PDF on WhatsApp from the finalized screen.
• Stock you can read at a glance. Every variety shows current sq.ft, its
rate, and a colour-coded bar (red when low). Receive stock with a
number, deduct it on every invoice.
• Real party ledger. See opening balance, every invoice, every payment,
the running outstanding — in chronological order.
• Reports that match the month. Total sales, GST collected, top parties,
top varieties, average order — by FY, by your fiscal year.
• Designed in India, for India. Indian currency formatting (₹1,23,456),
Indian FY (April → March), state-code GSTIN handling.
